The screen of the present invention is primarily adapted for use on wooden sash windows having a blind stop. It is to be understood however that the present invention is not limited to such use, but may be readily adapted for use on all types of window construction. In the illustration selected for the purpose of this application, a wooden window sash having a blind stop has been shown but any required modifications for use with other types of windows will be readily apparent to those skilled in the art to which the invention pertains.

ice

The blind stop consists of an upper member 10 and side members 11. The sill of the window is shown at 12 and the screen is generally shown at 13. The screen is adapted to cover the entire window opening. An upper bar 14, having a U-shaped channel 15 therein, is utilized for supporting and holding an upper end of the screen designated at 16. This portion of the screen 16 is rolled and inserted into the U-shaped channel 15 as shown in Fig. 2. The rolled upper edge 16 may be slidably contained in the U-shaped channel 15 for ease of adjustment and assembly of the device.

The top portion of the upper bar 14 has elongated slots 17 at spaced positions therein. Inserted through the elongated slots 17, are holders 18 which are riveted to the upper portion of upper bar 14 as at 19. The holders 18 have parallel end portions 20 and 21, interconnected by a central portion 22 in such manner that the portions 20 and 21 are spaced from one another and in diiferent spaced parallel planes. The end portion 20 has a hole 23 therethrough for riveting it to the upper bar 14 as shown at 19. The lower parallel end portion 21 has a slot 24 therein. This slot has a plural function including permitting storage or hanging of the screen when not set in awindow. This slot also allows hanging for cleaning or the like.

An upper bracket 25 consisting of two portions set at right angles to one another, as shown in Fig. 4, is utilized for coacting with the holders 1%. An opening 26 is provided in one portion of upper bracket 25, whereas the other portion of the bracket has an elongated slot 27 and a narrow entrance mouth 28. As can be seen from the drawings, the end portion 21 of holder 18 is of narrower width than the remainder of the holder. The Width of this portion 21 is substantially the same as the width of the opening 23.

In use, the upper bracket 25 is fastened to the upper member 10 of the blind stop, and flush with the outside edge thereof, by means of a screw inserted through the opening 26 as shown in Figs. 1 and 2. The screen and the upper bar connected thereto are assembled in position on the brackets 25 by inserting the narrowed end portions 21 of holders 18 through the mouth 28 of the upper in a manner similar to the upper edge 16. A lower bar 30 shown in detail in Fig. 2 is provided. This lower bar 30 has a U-shaped channel 31 formed in the upper edge thereof. The rolled lower edge of the screen shown at 29 is slidably inserted in the U-shaped channel 31 and supports the lower bar 30 from the lower edge of the screen when not in assembled relationship as regards a window opening. The central portion 32 of the lower bar is substantially in the same plane as the free edge of the bar forming the U-shaped channel 31 and extends downwardly therefrom. The lower end 33 of bar 30 is offset at an angle from the central portion 32, as shown in Fig. 2 of the drawings. The purpose of this angular disposition ofthe parts 32 and 33 will be apparent hereinafter. Additionally, the free edge 34 of lower end 33 7 3 wardly extending portions 42 having bent edges 43. Between central portion 32 of lower bar 3% and leg 39 of the lower holders 37, there is slidably inserted a seal bar 44 haying an angular offset lower end 45. The seal bar 4 t is slidably contained in this space for the purpose of permitting an insect tight and water tightconnecti'on with the sill 12 as shown .in Pig. 2.

The lower holders 37 form one portion of the locking mcrnsfor the screen. A locking catch having adjustable tension is generally designated at es. This consists of a side plate 47 having elongated slots 48 therein which end in circular openings 49. The side plates are adapted to be secured to the side members 11 of the blind stop as shown in Figs. 2 and 3 by means of screws 50 which ,7

manipulation of the catch lever. A cam portion 55 is provided on catch lever e3. This cam portion 55 is offset with respect to the pivot point at 52. This, as will be seen hereinafter, prevents the earn from slipping or from opening inadvertently. Pins 56 are also provided on side plates 47, at right angles thereto, as shown in Fig. 3. These fins 56 serve the purpose of guiding the screen smoothly up the side of the blind stop on which the screen is attached.

in assembling the screen for use in a. window opening, the upper bar 14 is held in position against the upper member" 1%) of the blind stop, and amarlc is made against the blind step through the slots 24. In addition to the functions of the slots'24 as previously set forth, they also constitute marking slots for the screws 57 which pass through the holes 26, as shown in Fig. 2, for securing the upper brackets to the upper member 10' of the blind stop. The upper brackets 25 are fastened to the blind stop, flush with the outside edge thereof. The holders 18 are then passed through the entrance mouth 28 of upper brackets 25 and then the wider portions 22 and 20 are inserted in the slot 27 and the screen will thereby be held in position. I

The lower holders 37 are then passed under the catch 46-as also under the tab 51' and catchlever 53. When assembling the screen in this manner the catch lever 53 is normally in the position shown in dotted lines in Fig. 1. The side plate 47 at this time is only loosely mounted on the side members 11 of the blind stop. After'the screen has been set under the catch, the lever 53 is turned downwardly into the position shown in full lines in Fig. l. The screws '59 are then tightened. The catch lever 53 is-then tightly pressed down to complete the tension.

Alter the foregoing operations have been completed,

the seal bar 44 can be adjusted into the position shown in Fig; 2, flush with the upper surface of the sill, and thereby the screen is made completely insect tight.

Normally the. construction of the screen as described hereinabove obviates a necessity for intermediate fittings on the screen proper or on the sill for holding the screen seen from Fig. 6, and extends through slot 59 in the lower bar'30. Additionally, however, the center catch 58 has a screw hole therethrough for accommodating a screw 60 which, when passed through the hole, is secured into the sill 12. This will positively prevent any buckling of the screen and further insures the safeness of operation.

The depressed area 35 formed in the lower end 33 of lower bar 30 permits the member 44, or seal bar, to exstruction keeps the screens tight and straight regardless of usage and time.

The ease of installation provided by the present invention will be apparent from the foregoing discussion of the structure and method of assembly. Normally only four brackets are installed with six screws. An overall time of approximately five minutes is needed for the complete assembly and placing in operable position of the screen of the present invention.

Manifestly changes is details of construction and of materials will be readily apparent to those skilled in the art to which the present invention pertains without departing from the spirit and scope of the invention as defined in the appended claims.
